Abstract
A transition coupling system for use with a dual containment pipe which includes an inner primary pipe and an outer secondary pipe with an interstitial space therebetween, the transition coupling comprising. The transition coupling includes an inner body configured to engage an inner surface of the primary pipe and an outer body configured to engage an outer surface of the secondary pipe. The outer body includes at least two releasably attachable portions, at least one of which is movable relative to the other in a radial direction thereof. The inner body and the outer body are configured to define a gap therebetween when coupled to the piping system such that the gap is generally sealed and in communication with the interstitial space.
